An integrated CAD/CAE system for cold forging process design

Some progress on a research project aimed at designing and developing a computer assisted Ienvironment for the . design of preforrning tsequences for cold forging are.· presented arid discussed .. The main focus is on the "Generate, Test and Rectify" mechanism. which controls 'the . sequence design process, as well as on the classification andstructure of the rules in the knowledge-based system. Details are given on logic and capabilities 'of the two modules devoted, respectively, to generate and analyse for suitability the' formingsequences for 'multi-stage cold forging of solid and hollow rotationally symmetric. Some application examples end the paper.
